Definitions

  • a mobile procuring unit can be, for example, an electrically driven motor vehicle, which is equipped for the purpose of receiving electrical energy from another electrically driven motor vehicle during a charging process and which requests energy.
  • the preferred route of travel is the route of travel with the shortest distance and the possible routes of travel comprise those routes of travel that also lead to the travel destination and whose additional distances are less than a value that is defined by the driver or by the autopilot.
  • the central computer can accordingly determine possible combinations not only on the basis of the current geographic position, but also on the basis of the intended routes of travel. Accordingly, in the creation of the evaluation values, it is possible to take into consideration whether at least one of the partners must travel over a distance that differs from its planned distance. This can worsen the evaluation. The advantage thereby ensues that the central computer can plan even further in advance.
  • An enhancement provides that the supplier units and the procuring units are controlled in an automated manner at least during an energy transfer process. In other words, at least during an exchange operation, the control of the motor vehicle is taken over by an autopilot, which brings the two combination partners together. This results in the advantage that the two combination partners can be brought together reliably.
  • Belonging to the invention is also a supply vehicle, which is equipped to transmit supply signals and/or demand signals to the central computer and to receive coordination signals from the central computer.
  • the supply vehicle is equipped to drive in an automated manner with a degree of autonomy of Level 5.
  • the supply vehicle comprises an energy storage unit with an energy storage unit capacity of at least 100 kWh and, in the rear end region and/or in the front region, a respective charging coupler, which is equipped to establish a charging process and a communication process with another vehicle during driving operation.
  • the charging coupler is equipped to transfer energy with a power of at least 100 kW during an energy exchange by means of a direct current fast charging process.
  • the invention also comprises an electrically operated motor vehicle that is equipped to drive autonomously with at least a degree of autonomy of Level 3.
  • the electrically operated motor vehicle is characterized in that that it is equipped for transmitting supply signals and/or demand signals to the central computer and for receiving associated coordination signals from the central computer.
  • the motor vehicle In the rear end region and/or in the front region, the motor vehicle has a respective charging coupler, which is equipped to establish an energy exchange and a communication link with another vehicle during driving operation, wherein the charging coupler is equipped for transferring a power of at least 100 kW during an energy exchange by means of a direct current fast charging process.
  • a degree of autonomy of Level 3 means that the motor vehicle is equipped so as to be able to drive in a highly automated manner.
  • Belonging to the invention are also enhancements of the method according to the invention that have features such as those already described in conjunction with the enhancements of the motor vehicle according to the invention. For this reason, the respective enhancements of the method according to the invention are not described here once again.
  • the described components of the embodiments respectively represent individual features of the invention, which are to be regarded as independent of one another and which the invention respectively further develops also independently of one another, and accordingly also are to be regarded, individually or in combinations, different from the combination shown, as a part of the invention.
  • the described embodiments can also be supplemented by additional features of the invention that have already been described.
  • FIG. 2 shows schematically the possible interactions between the electrically operated motor vehicles 4 , 5 , 5 ′ and the central computer 2 .
  • the participating motor vehicles 4 , 5 , 5 ′ can transmit supply signals S 1 and/or demand signals S 2 to the central computer 2 and receive coordination signals S 3 from the central computer 2 .
  • Shown in the figure are possible combinations of energy transfer processes L 1 , L 2 , L 3 a , L 3 b . It may be the case that, on the basis of the transmitted demand signals S 2 and the transmitted supply signals S 1 , an evaluation value for a combination of a charged electrically driven motor vehicle 5 and an empty electrically driven motor vehicle 5 ′ is selected.
  • the supply vehicle 5 ′ acts as a mobile supplier unit 1 and the electrically driven motor vehicle 5 ′ acts as a mobile procuring unit 3 . It may also be the case that an intermediate connection of a supply vehicle 4 is selected.
  • the central computer 2 transmits coordination signals S 3 to a first electrically driven motor vehicle 5 , to the supply vehicle 4 , and to the ultimate electrically driven motor vehicle 5 ′.
  • a first energy transfer process P 6 transpires in this case between the initial mobile supplier unit 1 and the supply vehicle 4 , which, in the substep L 3 a , acts as a mobile procuring unit 3 ′.
  • FIG. 3 shows an electrically driven motor vehicle 5 , which can comprise an energy storage unit 6 , a control unit 7 for an autopilot, a communication unit 8 , and two charging couplers 9 , which are respectively located at the front end and rear end of the motor vehicle.
  • the control unit 7 can be equipped in such a way that an automated driving with a degree of autonomy of Level 3 or 4 is possible.
  • the charging couplers can be equipped for transferring a power of at least 100 kW by means of a direct current fast charging process.
  • the charging coupler can also be equipped for communicating with the combination partners during a charging process. In this way, it is possible to prevent any overcharging of an energy storage unit 6 .
  • the communication unit 8 can be equipped in such a way that a communication with the central computer 2 is possible.
